FLUTE ORGAN PIPE.

Application filed June .10, 1922. Serial No. 567,272.

To all whom it may concern Be it known that I, GEORGE J. ZIMMER, a citizen of the United States, and resident of VValtham, county of Middlesex, State of Massachusetts, have invented an Improvement in Flute Organ Pipes, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in organ pipes and the object thereof is to provide a novel organ pipe of the labialtype in which a wind sheet is delivered across the mouth from a discharge orifice in a conduit located externally of the pipe. I

More particularly the object of the invention relates to improvements in pipes adapted to produce a tone which simulates the tone of an orchestral flute.

A further object of the invention is to provide an organ flute tone pipe in which the relative position of the discharge orifice of the conduit, which produces the wind sheet, may be adjusted relatively to the mouth of the pipe to produce the desired tonal effect.

A further object of the invention is to provide an organ pipe with a conduit adapted to deliver a wind sheet across the mouth ofthe pipe in which the form of the delivery orifice may be varied or adjusted to produce a desired wind sheet.

A further object of the invention is to provide a novel form of organ pipe comrising a body having a mouth, and a foot 1n which a partition extends across said pipe at a distance below the mouth, with means for delivering a wind sheet from said foot obliquely across said mouth whereby a novel tonal effect may be produced. i

A further object of the invention is to provide an adjustable conduit of pliable material having a permanent set for directing the wind sheet across the' mouth of the organ pipe in order that the position of the deivery orifice relatively to the mouth may be varied to produce a desired tonal effect,

'means desirably being provided for securing theend of the conduit fixedly in position when properly, adjusted. 7

Other ob 'ects and, features of the invention will more fully appear from the following description an the accompanying drawing and will be pointed out in the claims; I

The principal object of the invention is so to construct and treat an organ pipe that it will. give a true reproduction or simulation of the tone obtained by an orchestral flute. Usual organ pipes of the labial type comprise body, which may be open or closed, having at its lower end a mouth and below the mouth a foot in'which air under pressure is introduced. A block or languid, located just beneath the mouth of the pipe, extends nearly across the pipe, but is separated from the portion of the wall of the pipe at the mouth by a narrow opening through which the wind sheet is delivered against the edge of the upper lip of the mouth of the pipe. By varying the form, material and construction of the pipe various different tones have been produced by pipes of this character and certain pipes have been produced which more or less closely imitate the tones of the orchestral flute.

By the present invention the tone of the orchestral flute may be more accurately reproduced than in pipes heretofore constructed. This is accomplished by delivering the wind sheet from an orifice located externally of the pipe across a circular mouth in a slanting direction, preferably in a direction inclined toward the longitudinal axis of the pipe, and by providing a specially constructed conduit which may be adjusted relatively to the mouth and in which the character of the orifice may be also suitably varied to produce desired tonal effect.

A preferred embodiment of the invention is illustrated herein as embodied in an organ pipe of the labial type. In the drawing: Fig. 1 is an elevation of an organ pipe embodying the invention;

Fig. 2 is a detail longitudinal sectional view through the lower portion of the body of the pipe, the mouth, the foot and conduit for the wind sheet, on line 2-2 Fig. 1;

Fig. 3 is a horizontal sectional view of an organ pipe on line 33 Fig. 2; and,

Fig. 4 is an elevation of a muted flute pipe embodying the invention.

The organ pipe illustrated in the accompanying drawing comprises a. tubular body 1, which may be constructed of wood or metal, and which preferably is cylindrical in cross section. The lower end of the body 1 is provided with a mouth 2, preferably of circular form. Ears 8, located at opposite sides of the mouth and extending in a direction to the axis of the pipe, serve to confine the wind sheet.

The pipe also comprises preferably conoidal toot portion 4 having in its lower end or toe an aperture through which air nder pressure is introduced into the foot portion of the pipe.

The pipe is provided with a partition 6 which extends completely across the pipe at a distance below the mouth and produces a pocket 7 which assists in obtaining the proper fiute tone. It also separates the bod portion of the pipe from the foot so that air cannot pass from the foot into the body or the pipe as is usual in labial organ pipes.

The wind sheet which is delivered across the mouth of the pipe is produced by a conduit S which communicates at its lower end with the chamber in the foot 4 of the pipe and at its upper end is provided with an orifice 9 which is located externally of the pipe adjacent to the mouth and is adapt-- ed to deliver the wind sheet preferably in a direction inclined toward the longitudinal axis of the pipe, the wind sheetthus produced being confined by the ears 3 above described.

The conduit 8 desirably is of pliable material preferably sheet metal or extruded tubular metal which will when bent retain a permanent set.

By reason of this construction the position of the orifice 9 in the end of the pipe relatively to the mouth may be adjusted to produce a. proper tonal effect. When thus produced the conduit desirably is fixedly secured in a proper adjusted position. For example, if the conduit is formed of a pliable metal it may be bent to the desired position and secured to the ears 3 by lines of solder 10.

The pliability of the material of the conduit also enables the mouth to be bent into the necessary shape to deliver the required form of wind sheet.

As illustrated in Fig. 3 the conduit is flattened in such a manner as to deliver practically a fiat wind sheet slightly exceeding the diameter of the mouth 2 and is positioned to deliver the wind sheet in a direction obliquely across said orifice toward the axis of the pipe.

It will, however, be understood that the delivery conduit may be positioned to deliver the wind sheet in other directions if so desired.

It has been found that by adjustment of the position of the delivery orifice of the conduit difierent tonal effects may be produced and that the tone or quality may be modified by v rying the shape of the delivery orifice. It has also been found that the partition 6 must be located accurately at a predetermined distance from the mouth of the pipe in order to produce the desired tone and quality and that by proper correlation of the features heretofore described a substantially perfect flute tone ma be produced by an organ pipe.

Fig. 4 illustrates a muted fiutc pipe in which the body 11 converges "from the mouth end of the pipe toward the upper end. Such a pipe produces a modulated or softened fiute tone.

The organ pipe is illustrated herein as constructed of metal and of cylindrical. form. It will be apparent that the pipe may be made of vood in which case the foot a desirably would be cylindrical instead oi": conical. The organ pipe may be of square or of other cross s. .tions than the circular cross section shown.

It willbe understood that the embodiment of the invention disclosed herein is of an illustrative character and is not restrictive and that various changes in form. construction and arrangemeut of parts may be made within the spirit and scope of the claims.

Having thus described my invention. what I claim as new. and desire to secure by Letters Patent, is:
